SPINNING STOP MOTION Filed Febfl6, 1929 j HZ L I Patented Apr. 8, 1930PATENT OFFICE FLOYD '1. NOAH, OF GREENSBORO, NORTH CAROLINA SPINNINGSTOP MOTION Application filed February 18, 1929. Serial No. 340,591.

This invention relates to new and useful improvements in spinningmachines, and particularly to stop motions therefor.

In spinnin machines, great waste 1s ex- 5 perienced by t e running overof the bobbins, thereby causing tangling of the yarn, and necessitatinthe unwinding and straightening out of t e yarn. A considerable amountof yarn is lost, and the labor required to straighten it out is loss ofmoney to the manufacturer. The operator must kee a close watch on themachine, and be rea y to stop the machine instantly before any of thesethings occur, to prevent the loss of time and material.

One object of the invention'is to provide a device which will overcomethese .difliculties, and permit the machine to be automatically stoppedbefore such things occur.

Another object is to provide a novel and improved means whereby thetraverse is utilized to effect the stopping of the driving means of thespindles, when such traverse reaches the upper ends of the spindles orbobbins, or before the yarn becomes tangled or broken.

Another object is to provide a device of this character which is readilyadjustable so that the traverse may stop the machine at any desiredpoint.

Other objects and advantages will be ap-,

parent from the following description when taken in connection with theaccompanying drawing.

In the drawing:

Figure 1 is an elevation of a portion of a spinning machine showing theinvention applied thereto. I

Figure 2 is a top plan view of the same.

Figure 3 is an'enlar ed vertical sectional view through the circuitbreaker 20.

Referring particularly to the accompanying drawing, 10 represents aportion of the frame of a spinning machine, in connection with which thepresent invention is particularly adapted for use. This frame has therail 11 on which are mounted the spindles 12, which receive yarn, as iswell understood, such spindles bein provided with the pulleys 13, drivenby t e belts 14, from the main driving drum or shaft 15, which in turnis driven by the electric motor 16, located at one end of the spinningmachine. Operable vertically, in a reciprocatory manner is the ringrail, or traverse 17, such traverse being op- 5 erated by the well knownbuilder motion, a portion of which is illustrated at 18, and 19,respectively. Mounted below the rail 11 is a circuit breaker box 20,within which are disposed the spaced contact members 21 and 22, co andsuspended above these contacts, for movement toward and away therefrom,is a reciprocable rod 23, the lower end of which is provided with a head24 adapted to simultaneously engage the two contacts to close a circuit,said rod being properly guided in an opening 25, in the upper end of thebox. Secured to one end of the traverse 17, and extending therefrom, isa plate or arm 26, hav- I ing an opening 27 therein through which isslidably received the upper portion of the rod 23. Detachably andadjustably secured on the upper end of the rod 23 is a collar 28, whichis arranged to be engaged by the apertured end of the arm 26, when therail or' 7 traverse rises far enough to engage therewith, and when saidarm engages the collar and lifts the rod, said rod will be elevated fromengagement with the contact members 21 and 22, to break the circuit. Anautomatic electro-magnetic switch 29 is connected with the contactmembers 21 and 22, and with the motor 16, so that when the rod 23 iselevated by the traverse, and the lower end of said rod is disengagedfrom the contact members 21 and 22, the circuit will be broken in theautomatic switch 29,- whereby to stop the motor, and consequently, themachine. It will be understood that, normally, the rod 23 stands withits lower end on the contact members 21 and 22, so that the current mayflow uninterruptedly to the motor, through the automatic switch 29, andpermit the proper operation of the machine.

It will be noted that the collar 28 is attached to the upper end of therod 23 by means of the screw 30, so that the operator may adjust saidcollar to the desired position on the rod, thus causing the traverse toen- 10.

gage therewith at such position as is desired to stop the machine.

What is claimed is: 1. In a spinning machine stop motion, the 5combination with the motor drlven spindles and the vertically movabletraverse thereof, of an electric circuit including said motor, a switchin the circuit including contact members, a reciprocable member normallybridging the contacts to maintain the circuit, and means on the traversefor engaging and moving the reciprocable member to break the circuit andstop the machine.

2. In a spinning machine stop motion, the combination with the motor fordriving the spindles and the traverse, including an electric circuit, ofa circuit breaker including spaced contacts in said circuit, anapertured arm on the traverse, a switch in the circuit and controlled bysaid circuit breaker, and a vertically reciprocablc rod disposed throughsaid arm having its lower end normally bridging said contacts andadapted to be elevated from said contacts by said apertured g5 arm.

3. In a spinning machine stop motion, the combination with the motordriven spindles and the vertically movable traverse of a spinningmachine, of an automatic switch, a circuit breaker for controlling theautomatic switch including a circuit closing member arranged in the pathof the traverse and adapted to be engaged and moved thereby to open thecircuit breaker whereby to open the automatic switch.

4. In a spinning machine stop motion, the combination with the motordriven spindles and the vertically movable traverse thereof, of anelectric circuit including the motor, an

automatic switch in the circuit, a circuit breaker having contactmembers, and a reciprocable member engaged with the contact members andarranged in the path of the traverse to be elevated by said traverse toopen the circuit in the circuit breaker, whereby to open the automaticswitch and stop the machine.

In testimony whereof, I affix my signature.
